What to do after we cloned a ServiceNow instance?

Many ServiceNow customers clone their production instances into their test or development environments. What to do if you are mirroring an instance that has been overridden by a clone? Please perform the following steps:

Export all your synchronizations into an XML file

Delete all synchronizations

Import the XML file again

Perform an initial synchronization

The reason to export and import the synchronizations is that SnowMirror stores references to ServiceNow meta-data. However the cloning procedure completely changes the meta-data so it is necessary to renew the references.
